Transmission / Primary Oil Capacities

Discrepancy in the 1991 FSM. It shows 1.5 pints of oil for primary / transmission.11) 1991-1992 FSM corrected the 1991 book showing 40 oz for both years.12)

Note that for 1994-later, the manual says “Verify that lubricant level is even with bottom of clutch diaphragm spring.” Not higher or lower, but even with the diaphragm spring. It also includes this warning: “Do not overill the primary chaincase with lubricant. Overfilling may cause rough clutch engagement and incomplete disengagement (or clutch drag).”
